pwndbg_da

Dump a string from a memory address in a debugging session, with configurable maximum length.

Instructions

Dump a string at address (WinDbg-style).

pwndbg command: da Source: pwndbg/commands/windbg.py Category: WinDbg

Args: session_id: The UUID of the session. address: Address of the string. max_len: Maximum length to display (default: 256).

Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations exist, so the description should fully disclose behavior. It only states it dumps a string with an address and optional max_len, but does not explain how the string is read (e.g., null-terminated or fixed length), error handling for invalid addresses, or output format.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is structured with a summary line, source/category info, bulleted args, and a reference link. It is mostly concise but includes extraneous details (source file path, category) that do not aid tool invocation.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Even with an output schema, the description fails to explain return behavior or error conditions. For a debugging tool, information about how the string is read (e.g., null-terminated) and error handling is missing, reducing completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description adds meaningful descriptions beyond the input schema's bare titles: session_id as 'UUID of the session', address as 'Address of the string', and max_len as 'Maximum length to display (default: 256)'. This compensates for 0% schema description coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it dumps a string at an address, using the verb 'dump' and specifying the resource as a string. This distinguishes it from sibling tools that dump other data types (e.g., bytes, doublewords) within the WinDbg-style command family.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives. It does not compare with similar tools (e.g., pwndbg_strings or other dump commands) nor mention prerequisites or when not to use it.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
